How do I translate XML into perl variables?

I want to collect InstName and InstID attributes from each node as perl varaiable $InstName and $InstID, then enter $InstName and $InstID into a mysql table.

I think it is something like this:
$xs0 = XML::Simple->new();
$gv8apidata = $xs0->XMLin($returnXML);
print "InstID: $gv8apidata->{'DATA'}{'INSTDEFINITION'}{'InstID'} \n";

but I get error:
encoding specified in XML declaration is incorrect at line 1, column 30, byte 30
 at C:/Perl/lib/XML/ line 187

<?xml version="1.0" standalone='yes'?>

Attach the XML file.  What you posted doesn't give any problems.

Note that you would get the parameters you are looking for like:
    print "InstID=$xml->{INSTDEFINITION}[0]{InstID}\n";
Where the 0 is replaced with the index of which INSTDEFINITION for which you want the data, 0 through 2 in the XML you posted.  You can get the highest index with this:
    print "Highest index=$#{$xml->{INSTDEFINITION}}\n";

what does $xml represent in print "InstID=$xml->{INSTDEFINITION}[0]{InstID}\n";?

I changed:

$xs0 = XML::Simple->new();
$gv8apidata = $xs0->XMLin($returnXML);
print "InstID: $gv8apidata->{'DATA'}{'INSTDEFINITION'}{'InstID'} \n";

to this:

print "Highest index=$#{$returnXML->{INSTDEFINITION}}\n";

I tried using your code and get
Highest index=-1

does that make any sense?

I cant send the xml it is large.

I used $xml instead of $gv8apidata.  Just change the $xml in what I posted to $gv8apidata, and it'll work.

still get:
 encoding specified in XML declaration is incorrect at line 1, column 30, byte 30
 at C:/Perl/lib/XML/ line 187

$returnXML =~ s/UTF-16/UTF-8/;
because xml::simple only handles utf-8

Now I get:

not well-formed (invalid token) at line 313, column 83, byte 130100 at C:/Perl/l
ib/XML/ line 187
